Depending on which coil is energized, the output contacts will change from one position to another. The design of Arteche relay allows to have no consumption in permanence. ARTECHE latching relays range is designed to guarantee the best features and complete security even in the hardest working environment. The design, durability and quality of the different alternatives that ARTECHE latching relays can offer (FF range and standard range), make them suitable for high responsibility controls in different areas, highlighting: ELECTRICAL UTILITIES: Power plants, electrical substations. ›› Position monitoring of circuit breaker and sectionalizer ›› Direct operation on MV / HV (circuit breaker, sectionalizer) ›› Position memory: - manual / automatic - local / remote ›› Galvanic isolation between the control system and the primary equipment ›› Applications where high speed operation is a must ›› Applications where high breaking capacity is required ›› Tripping and lockout functions ›› Low duty loads control, activate digital inputs. FF range RAILWAY SECTOR: Electrification, signalling, interlocking and rolling stock. ›› Boarding doors locking ›› Brake circuit command ›› Lighting and air conditioned systems operation ›› Traction system ›› Low duty loads control, activate digital inputs.

E322124 UL Recognized Component Marks for USA and Canada: The combined UL signs for the USA and Canada are recognized by the authorities of both countries. All auxiliary relays identified with this mark meet the requirements of both countries. 6 Auxiliary Relays | Latching RANGE OF PRODUCTS General purpose latching relays The bistable ARTECHE relays with 2 stable positions. These positions are held by a permanent magnet, which prevents intermediate positions, giving a huge security operation. The position change is made with 2 sets of coils with separate entrances in BF3 and BJ8 and with breaking-flame contacts for each set of coils. Their pick-up time lower than 20 ms and the high breaking capacity of their contacts make them appropriate to be used as an interface between the protection system and the breaker. The main application for these relays is multiply the output contacts in those controls that need to memorize 2 stables positions: - automatic / manual - close / open Auxiliary trip and lockout relays ARTECHE offers specific relays intended to be used in tripping and lockout applications, where high quality requirement in operating time (with models that assure the trip ever in less than 10 ms) and breaking capacity are needed. Front indication on the nameplate, that indicates if the relay has changed the contact position. All the relays include a diode in parallel with the coil (see bistable relays with overvoltage protection characteristic). There is also the possibility of a bistable trip and lockout relay with manual reset. Latching relays with coil overvoltage protection ARTECHE’s auxiliary relays, either Vdc or Vac, have the possibility of including an element in parallel with the coil (diode or varistance). These elements aim to prevent the over voltage peak generated by the coil itself and it may affect other equipment installed on the same line.

Auxiliary Relays | Latching 13 BREAKING CAPACITY The breaking capacity is a critical parameter on the design and the applications of the relays. Its mechanical life could be considerably reduced, depending on the value of the load (especially with heavy duty loads), the number of operations and the environmental conditions in which the relay is operating. In any configuration, ARTECHE’s auxiliary relays have a high breaking capacity values. These limits are showed in the table below, in terms of power and current values. In all the cases, these relays guarantee a right performance during 50,000 operations. Likewise, the values showed in the following charts have been obtained in standard conditions in the laboratory, and they could be different in real conditions. In any case, the possibility of connecting serial contacts or a bigger distance between contacts makes these values to be considerably increased. 24 Vdc voltage Different loads configurations.

The charts show two different curves: ›› 1 contact: Breaking capacity of the relays with distance between contacts = 1.8 mm. ›› 2 contacts: Breaking capacity for relays with serial contacts, and distance between contacts=1.8 mm. The distance between contacts is shown in the tables of technical data. HOW THE BREAKING CAPACITY CAN BE INCREASED ARTECHE’s auxiliary relays are power relays, designed specially to have a high breaking capacity. Thus, there are applications where the loads are so high that it is necessary to even increase the breaking capacity, keeping the reliability of the contacts of the auxiliary relays. Thus, ARTECHE relays have the following alternatives and recommendations: ›› Possibility of external connection of equipment (serial contacts) getting an important increase of breaking capacity in these equipment is shown, guaranteeing the right performance during a high number of operations.
